KEY MESSAGES

- No hazards are expected in the week ahead as near normal weather gives way to a gradual warming trend through next week.

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 1232 AM CST Sun Nov 15 2026

High pressure will persist through Wednesday, with a gradual modification of temperatures through this period as well as gradual increase in southerly winds. The wide diurnal range will continue to bring cool nights, though not as cold as this morning's chilly lower to mid 20s, but rather a few degrees milder each night starting Sunday night, continuing through Tuesday night. Highs will be a in the upper 40s to low 50s today, a couple degrees milder than yesterday, and that will eventually see highs in the mid to upper 50s by Wednesday. The period remains confidently dry, with clear skies to high clouds cover at times.

LONG TERM /WEDNESDAY THROUGH SATURDAY/

Issued at 1232 AM CST Sun Nov 15 2026

Though our dry weather lasts through Wednesday, the upper pattern is expected to shift towards a more amplified western trof, eastern ridge in the CONUS by Wednesday. This will lead to a few periods of rainfall chances in the extended forecast. The first is a warm advection band of showers possible late Wednesday night and Thursday morning. This is a low confidence, low POP forecast at this time, represented by 10-20% rainfall chances, and zero QPF at the moment.

There is now enough signal for a short wave ridge in the area Thursday afternoon and night that the NBM has removed the low POPs that were previously there. The upper trof is then expected to see more energy lift out towards Friday and Saturday with rain chances in the 25-80%. This seems to be heavily influenced by the bullish ECMWF output in the model blend, but is also shown in some GFS ens members. Regardless of these pops, this late week forecast remains well above normal, with highs in the 60s, lows in the 45-52 range and several days of breezy southwest winds.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1114 PM CST Sat Nov 14 2026

High pressure will remain over the region with clear skies or very thin high clouds with excellent visibility through the next 24 hours. Winds will be light, and variable through the period.
